**Question: **The average scores of the class for exam are as follow:

Average score of the boys = 90

Average score of the girls = 81

Average score of the class = 84

Find whether Class contains more Boys or Girls?

**Answer:**

Assume that there are B boys and G girls in the Class.

Hence from the given data :

90*B + 81*G = 84*(B+G)

90B + 81G = 84B + 84G

6B = 3G

2B = G

Hence number of Girls in the Class are twice the number of Boys.
